Abstract The following article presents experimental use of different ways inguinal connecting aircraft elements using TIG (Tungsten Inert Gas), MAG (Metal Active Gas) and arched coated electrode. object the research were samples rotorcraft elements, which connected to each other by TIG, methods main aim was determine selected mechanical properties in particular hardness strength joints then, b...

To assess the exposure of welders to thorium-232 (232Th) during tungsten inert gas arc (TIG) welding, airborne concentrations of 232Th in the breathing zone of the welder and background levels were measured. The radioactive concentrations were 1.11 x 10(-2) Bq/m3 during TIG welding of aluminum (TIG/Al), 1.78 x 10(-4) Bq/m3 during TIG welding of stainless steel (TIG/SS), and 1.93 x 10(-1) Bq/m3 ...

Efficient electrocatalysis is most likely an answer to recent energy related challenges. Countless studies have been trying find the links between electrode/electrolyte interface structure, its composition, and resulting activity in order improve performance of numerous devices, such as electrolyzers, fuel cells, certain types batteries. However, this scientific field currently meets serious co...

Abstract Electrochemical reduction processes of oxides in molten salt have been proposed as the carbon-free technologies order to achieve carbon neutrality. The anodic behavior La 1 −x Sr x FeO 3− δ an O 2 evolution anode LiCl–KCl at 723 K was investigated. results suggested that K, electrical conductivity 3 −δ tended increase with doping. reactions 1− electrodes were characterized by electroch...

The results of wastewater treatment textile enterprises in the electrolyzer with insoluble anodes and separation electrode spaces an inert membrane are presented. influence time, current density, concentration sodium chloride, initial dyes on process electrochemical destruction is determined. developed technology makes it possible to ensure effectiveness organic substances, which necessary obta...

While numerous reference electrodes suitable for aqueous electrolytes exist, there is no well-defined standard non-aqueous electrolytes. Furthermore, are often large and do not meet the size requirements small cells. In this work, we present a simple method fabricating stable 3D-printed micro-reference electrodes. The prints made from polyvinylidene fluoride, which chemically inert in strong ac...

The development of alternative anode materials out of flexible composite nanofibers has seen a growing interest. In this paper, binary carbon nanofiber electrodes of SnO2/NiO and Sn nanoparticles are produced using a scalable technique, Forcespinning (FS), and subsequent thermal treatment (carbonization). The Sn/C composite nanofibers were porous and flexible, while the SnO2/NiO composite nanof...

In single site water or hydrocarbon oxidation catalysis with polypyridyl Ru complexes such as [Ru(II)(Mebimpy)(bpy)(H(2)O)](2+) [where bpy is 2,2'-bipyridine, and Mebimpy is 2,6-bis(1-methylbenzimidazol-2-yl)pyridine] 2, or its surface-bound analog [Ru(II)(Mebimpy)(4,4'-bis-methlylenephosphonato-2,2'-bipyridine)(OH(2))](2+) 2-PO(3)H(2), accessing the reactive states, Ru(V) = O(3+)/Ru(IV) = O(2+...
